This part's easy. The advantage of using this double ended stud is that I get 40% more strength from the increased tensile stress area, since it's not threaded, over all thread. This little gem has 120,000 psi yield strength, for those sideways pulls.
Plus I'll trim it down so the quick jack is actually on the shank, instead of the threads, for increased shear strength. The acorn, stover nut, and washer are all Grade 8. And that's the heavy-up.
